Abstract
Waveguide filters comprising ridges disposed within a waveguide cavity for selecting electromagnetic signals within a frequency passband. An apparatus includes a waveguide filter comprising a waveguide cavity and a plurality of ridges disposed within the waveguide cavity. The apparatus is such that each of the plurality of ridges comprises a first side and a second side, and wherein the first side and the second side are disposed at a non-orthogonal angle relative to one other. The apparatus is optimized for fabrication using metal additive manufacturing techniques.

An apparatus comprising:
- a waveguide filter comprising a waveguide cavity, wherein the waveguide cavity is defined by a plurality of sidewalls;
- and
- a plurality of ridges disposed within the waveguide cavity;
- wherein each of the plurality of ridges is attached to at least one sidewall of the plurality of sidewalls defining the waveguide cavity;
- wherein each of the plurality of ridges comprises a first side and a second side connected to the first side, and wherein the first side and the second side of at least one of the plurality of ridges are disposed at a non-orthogonal angle relative to one another;
- and
- wherein only one ridge of the plurality of ridges is attached to any one sidewall of the plurality of sidewalls at any single point along a length of the waveguide cavity.
